ADVACAM’s X-ray digital radiography imaging detectors are an ideal solution for many Non-Destructive Testing (NDT) applications. The photon counting detectors provide improved sensitivity, spatial resolution, contrast and signal-to-noise ratio. The broad range of detectable X-ray energy starting from 5 keV up to hundreds of keV or even MeV let the detectors capture from very light composite materials up to thick welded parts. In addition, the energy discrimination helps suppress the scattered radiation and improving the contrast of measured images. NDT specialists and service providing companies can extend the portfolio of customers by those whose products could not be inspected by X-ray radiography in the past. Our new X-ray imaging technologies are useful for inspecting composite materials in the aerospace industry.
Standard radiographic X-ray imaging provides a black and white intensity or density image of the inspected sample, where defects, impurities or cracks are observed if the resolution and the signal over the noise of the image is appropriate. The spectral NDT X-ray imaging based on photon counting provides additional material information of the samples together with a superior contrast and high spatial resolution. The spectral material information is used to discriminate different materials and identify the materials of interest. The spectral image taken with WidePIX 5x5 CdTe of a PCB unveils different components in different colors.
